Cold Starting Long Standing Engines

First thing I would do is squirt a bit of oil in the cylinders and rotate by hand a few times.next is a must remove both valve covers and prime the oil system by hand with a drill and make sure you get oil up to all the rockers. You will need to slowly rotate the engine to line up the oil passages through the cam to the rockers. If that’s successful replace the valve covers and fire it up. I’m no expert either but that’s what I would do.
